Distinguish cytokinesis from karyokinesis.

उत्तर
| Cytokinesis | Karyokinesis | |
| 1 | Cytokinesis is the division of the cytoplasm of cell. | Karyokinesis is the division of the nucleus of a cell. |
| 2 | It occur at the end of M-phase, after the neculear division is over. | It occur during M-Phase of cell cycle before cytokinesis begin to proceed. |
| 3 | Stages such as prophase, metaphase, anaphase, and telophase are not present in cytokinesis. | It is divided into four stages: prophase, metaphase, anaphase, and telophase |
